Map Viewing Service (WMS) of the dataset: PPRT SOGEPP (Origin of Surface Risk)

The origin of the risk characterises the real-world entity which, through its presence, represents a potential risk. This origin may be characterised by a name and, in some cases, a geographical object locating the actual entity causing the risk. The location of the entity and the knowledge of the hazardous phenomenon are used to define the risk pools, the risk-exposed areas that underpin the RPP.In RTPs, it represents the enclosure of the facility(s) classified for environmental protection (ICPE) at the origin of the risk analysed and addressed by the RPP. In the PPRT methodology, it is described as a grey area.

风险源指一类现实实体，其存在本身即构成潜在风险。该风险源可通过名称予以表征，部分场景下还可借助用于定位实际致险实体的地理对象来补充说明。实体的位置与对危险现象的认知，可用于划定风险池（risk pools）——即支撑RPP运行的风险暴露区域。在RTPs中，该风险源指代经RPP分析与处置的风险源头处的环境保护分类设施（ICPE）的围合范围。在PPRT方法论框架下，该风险源被界定为灰色区域。
